Unsharp Mask: suggested starting values · Jun 5, 08:58 PM by Simon Mackie
Scott Kelby suggests using the following settings as starting points for Unsharp Mask (USM) in Photoshop. Give them a go:
| Subject | Amount | Radius | Threshold |
| Soft subjects | 150 | 1 | 10 |
| Portraits | 75 | 2 | 3 |
| Moderate sharpening | 225 | 0.5 | 0 |
| Maximum sharpening | 65 | 4 | 3 |
| All-purpose sharpening | 85 | 1 | 4 |
| preparing for Web | 400 | 0.3 | 0 |
Remember that these are just guidelines – oversharpened images always look terrible. Try these as a starting point, but if you get symptoms of oversharpening (grain in the image, and “halos” around objects), back off a little bit. And always check the image at at least 100% zoom.

One thing I always forget to do, sharpen my images.
Very nice guidelines.
